Ask questions and find answers on STM32 hardware set-ups, including schematic-related challenges, debugging probes, power configurations, and more.
On a serial product after a firmware update, there are some sporadic cases, where we get a hang up situation. It would be very helpful to know where exactly the program is stuck. According to ES0346 Rev. 6 chapter 2.8 it is possible to access progra...
Hello All,I have the following setup:Stand-alone STM32L4Q5CG on 48-pin breakout board with coupling caps installedPB11 tied to 3.3V via external 4.7K pull-up resistorPB9 tied to 3.3V via external 4.7K pull-up resistorSTM32CubeMx rev. 6.0.1 Firmware p...
Hi everyone,I do have 2 PCB boards based on STM32F030F4P6 MCU, the two PCBs have the same hardware and connection with other components, I read the first MCU's code using ST-LInk V2 -using SWD- and saved the .hex file to my PC then I wanted to re-pro...
Hello, I would like to know what LDO regulator you recommend to use in my development, it uses a 7.2V Lithium battery pack. The application uses 5 GPIO's (4 output, 1 input), 1 I2C, 2 USART, 1 LPUART.
Hi All,I am reading data from UART via polling method. I am sending random data on UART pins and reading on terminal. in that case my program is working fine in debug mode but when try to make this work without debug mode or I can say normal program ...
I have STM32H750 100pin chip and STLINK-V3MINI. Pin 9 of mini 14 pin connector has no obvious place on the chip. There is already a JTCK/SWCLK signal between 6/14 and PA14/STM32H. I am using AN4938 table 6 and UM2502 also table 6 to connect debug pin...
I have a board that is STM32H747I-DISCO which was bricked due to the power supply settings improperly set (Set to LDO when it shouldve been SMPS) in the code.The documentation say to boot with BOOT0 pin set in order to restore the working image, I do...
Hello Community. STM32F030R8T6 seems to be unavailable. This is a huge problem. Does it exist a pin to pin an alternative (also on other families (STM32F1, F2, f3...).STM32F030RC is NOT a solution since it appears not to be available too. In any case...
Hi, I made a tool to flash/debug e.g. STmicro's (EBlink) that uses direct writing instead of external flash loaders. I noticed that the current speed step of the STlinkV3 goes from 8MHz directly to 24MHz with no jtag/swd speed settings in between. ...
